Tn all rif/imm t may colic/2m' Be it l-.noWn that Mou'roN l. ToTTLn, n, citizen oi the United States, residing :it Glyndon, in the county of Baltimore, State 5 of linryizu'id, have invented certain new end useful improvements in Vuioenizers, oi which the following is u speeiiiezition.

This in Vention relates to au improved oonstruction oie vulennif/,er particularly adapt- 1t\ed for heating and 'rulcenizing the. rubber cement used to secure together the butt-ends brush bristles, although thel invention muy be used for purposes other lthen that mentioned.

1.5 The object of the invention is to provide :in `improved construction of vuezniizer which `will accommodate e, number of hrushes at one tinu und which muy be reedily operated to apply pressure and heet to 20 the brush paris :it the particular point desired, und to ineke provision for preventm in;r the heet from injuring the bristles, means being also provided to accommodate brushes oi Various sizes.

The invention is illustrated in vthe eonipnnying drawings, Where-in7 Figure l, shows the machine in de elevetion. Fig. 2, illustrates the in end vation. 3, is un enlarged vertical sectional detail through one set of clamping :ind heating tables, :ind Fig. i shows a plan View of a. portion of u lower clamping und heating' trible with the brushes in position thereon.

In the drawing the numerul, l, designates suitable supports to which :i traine is rigidly zitiuehed,-the 'frame comprising vertical rods, 2, und, 3; horizontal side hars, et, und

end hars, 5-the side und end hars oon-- 40 neoting the lower :xndfiupner ends of the rods :ind forni un uprightreotzingulurfreine, The upright or Vertical hzirs 2, and, 3, :ire provided :it intervals het-Ween their lower :ind upper ends, with stationery heuring hors, (5, which extend horizontally between :und :ire rigidly secured to said vertical hers. 'lhese stationary henring hors :ire provided with eyes, 7, nt their ends through which the vertical lin-rs extend und :i Din, 8, or equivalent device is employed in the present instaure to rigidly secure the eyes to the rods.

'The hearings, 1Q, sustein horizontal shafts, 85- lei, which letter ef-tend between the upright rods, end, 3, each end of the said shalt Carries e Worin, 15, 'thatA meshes with und drives the worin gears 13, on the lower ends of vertical shafts ll. A suitable hand 7e Wheel, 1G, is provided on the end of each shaft', 1%, whereby the latter may be turned to effect s, revolution of 'the short vertical nits, il, at opposite ends of the horizonl shaft. 75. The hearing hars, 6, on rods, 2, sind those` embers, '3 are so arranged on the vertical rods thats her on rods, 2, and another on rods, f3, will here position in the same horizonel so they may sustain between su them s horizontal tniole, l?. reference to the cross-sectional View in Fig. 3, it Will he seen that these tables, l?, have a flat upper or horizontal surface, i8, and :i central 'circular here, l). The exterior Walls of S5' said tables nre preferably angular and in the present instance horizontal ribs, 20, are prorided on oppiisiie exterior sides thereof sind ai covering* of suitable material such as asbestos, 2l, is provided on the two vertical` 90 sides und bottom ot seid table whereby to prevent the loss of heut by radiation, but the horizontnl upper surface Vof seid table is exnosed :ind is without such covering. li); reference to Fig. l, it will be noted that the :ishestos covering' along' the opposite upper sA of the tz'xhle is beveled as at, 22,--tliis being' done for :L purpose which will presently he explained. y

leach vertienl rod, und, 3, at the oppo le@ site ends und corners of the table, 17, crries :1 bracket, 3S},--one end of which has an eye, Q4, which exnhrnees the rod and the other end oi which turns upwardly at the side of the table and sustains a horizontal shelf or support, Q5. lt will thus he seen that each shell' or support, 25, is sustuined at its ends hy the hrziekets on the rods nt opposite ends of the tnhle und that shelves are provided :at with horizontal longitudinal side edges 11u of the table. 011e edge, 26, of each shelt 0r support is beveled to correspond. substantially with the bevel 22, on the table top so as to form an air gap, 27, between the shelf and table. It will be noted that the upper surface, 18, of table, 17, and the upper surface of the shelves, 25, at opposite sides thereof are flush so that the object to be heated may be laid on the table with one end projected onto the shelf. This construction prevents injury to the bristles that rest on the shelf. At each end, the table, 17, carries a horizontal cross-bar, 28, which is secured .in place by means of rivets or other fastenings, 29, and the ends of said bars project laterally at opposite sides of the table surface, 18, and each end has an 11p-turned bracket or eye, 30, with a set-screw, 31, therein. Gage-frames are provided on the upper surface of the table,-one at each side of the said table and said frames have a bar, 32, that extends substantially throughout the length of the table and each end of the bar is provided with adjusting rods, 33, which are engaged by the eyes, 30, and screws, 31, on the cross-bars, 28. Obviously by loosening screws, 31, the rods, 33, `may be moved more or less through the eyes, 30,

and the bars, 32, moved toward or from the side edge of the table so that the ferrules, 3l,

Aof the brushes which are t0 be heated may have one end butted against the bars, 32, while the bristles, 35, will project across the gap, 27, and lie on the shelf or support, 25,

.as shown in Figs. 3 and 4, of the drawings.

Above each table, 17, the Vertical `rods, 2, and, 3, of the frame sustain movable bearing bars, 3G, each bar having eyes, 37, at its ends and also having a central bearing lug, 38, with al threaded opening therethrough to receive the threaded end, 12, of the short vertical shafts.

A heating and Clamping body, 39, is sustained at its ends between two movable bearing bars, 36, the bars themselves being supported on the vertical shafts, 11, as previously explained and consequently when said shafts are turned the heating and clamping body may be raised or lowered with respect to the table, 17, beneath it. The` heating and clamping bodies are substantially the same in construction as the tables,-being provided with a circular bore,i 40, and angular exterior walls of which three Sides are covered with asbestos or equivalent material and the bottom, 41, of which is left exposed for the heat to radiate there# from,

It is believed to be obvious from the foregoing description that the ferrule-end of the bristles which lave been cemented with rubber may be placed on the top or upper surface, 18, oi the table and the heating and clamping body then lowered thereon to rigidly clamp the ferrules onto the table and that if sulicient heat be passed through the ferrules and cemented brlstles that a vul canizatlon will follow.

The heating of the tables and also the,`

44, and enters the stationary table, 17, near the top surface and at one end and each branch is provided with a valve, 46. These supply branches, 45, are substantially rigid because the tables to which they lead are stationary and each supply branch communicates with the central bore, 19, of the table so as to supply steam to the latter at one end and near the upper surface.

The return connection from the bores, 19.

of thetables is made at the opposite end of the tables and near the bottom,-horizontal pipes, 47, serving to effect this return by tapping into a vertical return pipe, 48. These pipes, 4T, and, 48, may also be rigid because the tables from which they extend are stationary. It will thus be understood that in so far as the steam connectionswith the stationary tables are concerned they may all be substantially rigid, with the exception of course, ol." the allowance made for expansion and contraction, and the supply pipes entering the tables at one end near the top while the return pipes lead therefrom at the other end ynear the bottonrof sa-id tables. The supply and return pipes lor the heating and clamping bodies however must be arranged in such a way as to allow the said bodies to have a vertical movement and these pipes will now be described.

By reference to Fig. 1, it will be seen thata branch pipe, 49, extends laterally from a union, 50, at the upper end of supply pipe, 44, and said branch, 49, extends in substantially a horizontal direction and in a plane above the upper side bars, 4, of the frame. At the extreme end the pipo, 44, has conneotion with a header, 51, and pipes, 52, 53, and, 54, respectively extend in an inclined direction from the header, 51, and in a general direction back toward the vertical supply pipe, 44, as best seen in Fig. l. Y

From the lower end of pipe, 52, there is a depending pipe 55, in which a valve, 56, is located and the lower end of said depending pipe turns laterally and enters the top heating and clamping body near the upper side and one end of the latter. ln the same manner pipe, 53, carries a depending pipe, 57, in which a valve, 58, is located and this pipe is of greater length than pipe,

55, and ex 130 tens own to and eners the ntermeae heating and clamping body also .new ghe upper side enel at one end. The pipe, V also has a depening ppe connection, 5%, which is off greater length than either of Fee pipesv 553 and, 57,-:1nfl sale pipe, 597 :also n s e valve, 60, therein and its lower enel ene lle lippe? poon ehe lowe'nost hee I and clamping body new: one end.

From the foregoing eplennon will seen that '513e luee hea-.eilig and clamping bodies are h ated. oy steam tlm?, fll'eete or conveyed thereto through elle pipes, 57, and, 59, and lmt each ef these pipes is unsupported beween its point of oonneeton with s heating and elampn body enel the free end of one or the other o 53, or 54, which latter mey be .speling cause o-f their length Weln'ou; afeeng she joint between them and header, he springing of these pipes only bec-emes necessary when the clamping body to which tlxey are connected ai; then' lewe? enfs is moved vertically to clamp o1' ee series of brushes.

The return steam connections from 'elle sume Clamping bodies is also effect-eel oy means of pipes7 (S, 52t 62%, which are provided with vulves, 3,.e.n, 68? tively-the pipe, 6l, being the an@ leading ffonl the loWez pofrton of he depen most body down io en inelne-:l pipe,

the pipe, 62, being the next in length enclextendng down to en inclined pipe, 39 and pipe, 63, being the slugg'fest eennecng at its lower end with :1n nelnecl l? e, es shown in Fig. 2.
